Benefits of technology

[0011]A vertically accessible locking/adjusting mechanism is advantageous in comparison to side-locking mechanisms. For example, heavy patients with heavy thighs may be problematic when trying to manipulate

Problems solved by technology

The insertion of the applicator was associated with significant radiation exposure to the physicians handling the apparatus.
A potential difficulty that remains with cervical brachytherapy applicators is that a GYN applicator inserted into the uterus or the vaginal cavity may have a tendency to dislocate, e.g., by int

Embodiment Construction

[0029]FIGS. 1 and 2 are perspective views of an assembly 5 of a perineal retainer 100 attached to a CT compatible high dosage radiation (HDR) ring and tandem applicator 200 according to an example embodiment of the present invention. Although a specific applicator 200 is described in connection with the illustrated embodiment, it should be understood that any suitable applicator may be provided. For example, any applicator described in U.S. Pat. No. 7,666,130, which is hereby incorporated by reference in its entirety, may be provided for the applicator 200.

[0030]It noted that FIG. 2 shows the assembly 5 supported on a support cone for purposes of illustration. However, the cone does not form part of the assembly 5.

[0031]The perineal retainer 100, which is described in greater detail below, is provided as an accessory to an HDR ring and tandem applicator 200, such as the Mick CT Compatible HDR Ring and Tandem Applicator (e.g., the 32 mm set) commercially available from Mick Radio-Nuc...

Abstract

A device and method for retaining a position of a treatment applicator include a perineal retainer body configured to receive the applicator and form a positive stop with a perineum of a body of a patient, and a locking bracket configured to secure the perineal retainer body to the applicator. The locking bracket is movable between first and second positions with respect to the perineal retainer body, is configured to exert a clamping force to clamp the applicator, includes an actuator configured to move the locking bracket between the first and second positions, and is vertically accessible for securing and adjusting the applicator with respect to the perineal retainer body. The method includes securing a perineal retainer body to the applicator by a locking bracket, and attaching the perineal retainer body to a body of a patient.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of U.S. Provisional Patent Application No. 61 / 479,839, filed on Apr. 27, 2011, which is expressly incorporated herein in its entirety by reference thereto.FIELD OF THE INVENTION[0002]The present invention relates generally to a brachytherapy device and to a method for cervical brachytherapy treatment using a brachytherapy device. Radioactive therapeutics may be delivered to a region of the cervix, e.g., to provide for treatment of cervical cancerous tissue.BACKGROUND INFORMATION[0003]Brachytherapy is a form of cancer treatment in which radiation sources are placed inside a patient's body, e.g., to irradiate a tumor. In brachytherapy, a physician typically implants several radioactive seeds in or around a tumor, thereby providing a higher radiation dose to the tumor than would be possible with external beam radiation therapy. Careful placement of the radioactive seeds is critical to allow for local...
